IMPROVEMENT IN ADJUSTABLE BANDING-RINGS FDR HAT-BLOCKING MACHINES.

Specification forming part of Letters Patent No. 120,740, dated November7, 1871.

To all whom it may concern:

Be it known that I, GEORGE HAYDEN, of the city of Newark, in the countyof Essex and State of New lJersey, have invented. certain new and usefulImprovements in Adjustable Banding- Ring for Blocking orShaping-Machines, of which the following is a specification:

My invention relates to an expanding banding-ring adjustable to thevarious sizes of hats. It consists in an adjustable ring expanded andcontracted by slides, said slides being operated by a combination oflevers.

The following is a description of the accompanying drawing whichillustrates the improvement. h his the clamp which holds the hat-bodyrmly to the lower plate of the machine. a a is theadjustablebanding-ring made in two parts, one of which overlaps the other, eachpart being furnished with slots and rivets for the purpose of admittingof expanding and contracting to suit the various sizes of hats, and atthe same time holding the two parts iirmly together. b b are thecompressing-slides connected to the ring by arms sliding in suitableways or slots in or attached to the clampingplate h. They are operatedby fulcrum-levers d d, which are connected at one end to rods e e, andat their centers with the compressing slides bb, and held to their placeby sliding slots g g, adjustable in the bar j', which bar is ixed to theclampingplate h.

The mode of operating the banding-ring a a is by compressing one end ofthe fulcrum-levers d d, which in turn compress the slides b b, andcontracts the banding ring a a to the required size of the hat to beblocked, in which position it is held by the stops g g. The greatadvantage the adjustable expanding banding-rin g has over any other inuse is, th at but one ring is required to band all sizes of hats, thering being a part of the machine, and readily adjustable to any requiredhat size. The solid ring of ordinary machines requires to be detachedbodily. In blocking bell-crowned hats the expanding-ring will admit ofthe ready introduction of that shape of block in its expanded form, andobviate the necessity of expanding it after itsintroduction into thebody.

I claim as my inventionv The adjustable expanding banding-ring, operatedby slides and levers, substantially as set forth and for the purposeherein specified.

GEORGE HAYDEN.
